SBA deal structure
A seller note can reduce the buyer's cash requirement and help bridge a valuation gap — but only when structured correctly. Here is what full standby means, how lenders verify it, and when seller financing actually helps.
What is a seller note?
A seller note — also called seller financing — is deferred purchase-price debt owed to the seller. In an SBA acquisition, seller debt can serve two different purposes: a limited portion may be credited toward the required equity injection when the current SBA conditions are met, while other subordinated seller debt may help bridge a valuation or financing gap. Those two uses must not be conflated because their standby, payment, documentation, and debt-service treatment can differ.
When the required injection is 10% of total project cost, seller debt may be credited toward no more than half of the required equity injection. An illustrative structure is 5% qualifying buyer equity plus 5% seller debt on full standby for the life of the SBA loan, subject to lender confirmation.
Seller debt can reduce the senior SBA loan amount or bridge a valuation gap. Whether it improves DSCR depends on whether it is credited toward the injection, placed on full standby, or structured as other subordinated debt with lender-approved payments.
Seller debt that does not satisfy the current equity-credit conditions does not count toward the required injection. It is treated as other debt, and any payments included by the lender increase total annual debt service and can make the deal unfinanceable.
The standby rules
The key distinction is whether seller debt is being credited toward the required equity injection. Under the currently effective SOP, that credit is available only within a limited amount and only when the seller debt is on full standby for the life of the SBA loan. Other seller debt may have lender-approved subordinated terms but does not satisfy the required injection.
How it affects equity
The equity injection calculation is central to whether seller debt helps the buyer. Start with total project cost and the required injection, then separate qualifying buyer equity from seller debt and other financing. The lender verifies the final treatment.
Debt-service treatment
The DSCR treatment depends on the seller debt's purpose and approved payment terms. Seller debt credited toward the required injection has no payments while the SBA loan remains outstanding. Other subordinated seller debt may create current or future debt service that must be modeled.
What lenders verify
Lenders don't take a seller note at face value. They review the note terms, the subordination agreement, and the standby documentation before accepting the note as equity.
The note must be executed at or before closing. It must specify the principal amount, interest terms, maturity, payment restrictions, and whether the debt is intended to receive equity credit through full standby for the life of the SBA loan.
The seller must sign a subordination agreement placing their note behind the SBA lender in priority. The lender determines the required lien and payment subordination for the transaction.
A standby agreement must match the equity treatment being requested. For equity credit under the current rule, it must prohibit principal and interest payments for the life of the SBA loan.
Lenders don't require this, but the seller should understand that an installment sale structure affects how they report the gain — consult a tax advisor before agreeing to seller note terms.
In some deals the lender may ask the seller to pledge additional collateral against the seller note, or require a personal guarantee from the seller. This is more common on larger or higher-risk deals.
For deals where the seller note is unusually large, some lenders conduct basic due diligence on the seller's ability to perform on any representations and warranties — particularly if there is a material indemnification clause tied to post-close earnings.
